Prior to the beginning of the War, comic books were something that every kid had; making it a power form of media, which will become a powerful tool for the Office of War Information (OWI). Superman and Action Comics were some of the most popular comics during the pre-war era and will have influence during both the Pacific and European Campaigns. Superman was special in the way he had "fought" during the war. He had believed that facism was a human battle, and one that he could not fight.
During the New Deal era, Superman was a figure to be known as the "man of the people", often helping those whom had found trouble while working for the Civilian Conseration Corps. He has also, as shown, fought against slum housing that was prevelent during the Depression.
Prior to the bombing of Pear Harbor, the United States was in a period of isolationism, with Americans often blaming munitions manufacturers for the cause of war. Superman was featured in comics that had coincided with this popular belief. Superman is shown eavesdropping on munitions lobbyists.
The public opinion had begun to change in mid-1940 during the fall of France and the Battle of Britain. This was a turning point in Superman’s role in the American war effort. Comics had often shown Superman rallying against Fifth Columnists, a term used to describe those who are disloyal to their country or spies. Superman has taken into his own to save the vary munitions plants that he was starkly against only a year prior. In the comic books themselves, there was often a letter written by Clark Kent to members of the Superman fan club. The message: “The loyalty of individual citizens is being called on right now. Workers in all walks of life are proving their Loyalty by doing their utmost to hasten the great work of national preparedness.” The OWI used these themes to create propaganda posters depicting Superman calling for readers to purchase war bonds. The Treasury had also used Superman to encourage the purchase of stamps.

Although Superman was never seen directly fighting the Axis powers in the comics, he was depicted as a defensive character, helping those who are under attack, and cheering from the sidelines as a symbol of American strength.
